2020 Kia Sportage: check engine light

Filed Sep 27, 2026 · Engine · KS

My daughter's 2020 Kia Sportage S was purchased September 22, 2025 from a Nissan Dealership with 96,574 miles on it. It dove great. She used it less than 20 miles per day on residential streets to get to and from work and to church on Sunday. It was not used for interstate or freeway driving. By June of 2026, we noticed that it was requiring more oil between oil changes. The oil level was checked at least once every other week to see if more oil needed to be added. We were adding about a quart of oil every two to three weeks although there was no evidence of excess smoke coming from the exhaust. Then on my daughter's way to work on August 13, 2026 she experienced a sudden shaking of the car and the engine light came on. She immediately pulled over and turned off the engine. We were out of town at the time so my son came to see what was wrong with the car. He checked the engine oil first and it was within the right level. The car was limped to the local Kia dealership to trouble shoot it and they said that there was evidence of rod/bearing failure in one cylinder that was causing the shaking. There is no fix for it other than to replace the engine at a dealer discounted price of $6,600. Kia corporate is offering a $1,000 credit toward the repair and the dealership is contributing $4,040 to the engine replacement. The car has 103,510 miles on it now. The Theta II 2.4 engine had an engine settlement that covered model years through 2019. Ours is a 2020 that was built in May 2019 and has the same engine that failed under the engine settlement. But ours is not covered. We are still in the process of working with the local Kia Dealership and Kia Corporate to make it right on an engine that clearly has known problems causing premature engine failures. I have owned or recommended to family members to buy Kia/Hyundai vehicles and between all of us we have had 13 Kia/Hyundai vehicles. This may be the last Kia/Hyundai vehicle that we own...

While driving on the expressway posted speed 65 was doing 70, left lane driving, suddenly my check engine light started flashing, my oil light came on and my vehicle started slowing down. Acceleration was not an option, causing hazardous conditions to have to put my hazards on and cross two lanes of heavy traffic. Vehicle went into limp mode. Vehicle was caught up on an oil change, and was regularly checked and filled with oil. Oil seemed to have been burning rapidly or just simply disappearing. The motor blew and i purchased this vehicle less than 6 months ago. I only put 4,000 miles on it. 2020 kia sportage s, dealership was lilliston ford. Took vehicle to kia dealership to get two safety campaigns fixed. They informed me i was only a couple hundred miles over my warranty and my repairs are not covered. I now have an inoperable vehicle that i have payments on, which now needs a new engine. No recalls matching my vin, only my make, model and year. All repairs were denied. Worst vehicle decision ive ever made…

Car was driving, stopped at a stoplight, never moved again. 3 lights came on, Check Engine, Check Oil (Which had been serviced previously by a month and a half), and Check Battery. Bob Sight Kia has stated Engine issues associated with the rods failing and the starter not functioning due the the manifold, I am uncertain to the technical terms. It was late at night, the area only semi lit up and I had to wait for a tow in unsafe conditions as I was stuck in a turn lane. Prior to the failure, no issues. This is my only means of transport as a waitress, I had recently moved into this area and plan to move again at the end of year, so my car is much needed. From the theft issues of this car to the mechanical issues over the last year, I can honestly say I will not be buying a Kia again. What I need to know now is has the threshold been met by the standards you have set through complaints by consumers like myself and the manufacturer information that a recall or a means of financially assisting this situation exist yet? The repairs quoted are literally almost half of what I owe on the car left and I do not know what to do, but am hoping to hear from you.

In April of 2025, it was noticed that my Sportage was consuming oil. There were no leaks or smoke just having to put oil in. Two mechanics stated that’s just Kia. On the night of 1/30/2026 my Sportage had an engine light come on. After the winter storm, I was able to get the code read and it came back as a Cylinder 1 Misfire. In May of 2025 I replaced all coil packs and spark plugs. On 2/1/26 we replaced the coil packs and spark plug. On 2/4/2026, Kia told me I have to replace the engine. I am still paying the vehicle off. This does seem to be an issue with Kia engines 2.4 from what I’m reading.

Driving to grandmas Christmas weekend on the highway all of a sudden my car couldn’t keep speed was shaking the check engine light came on. Now my cylinder one psi is only 50. I have noticed over 100 complaints with very similar car issues. I just bought this car 5 months ago from a dealership. I have barely put 4,000 miles on the car myself.

The contact owns a 2020 Kia Sportage. The contact stated that while driving at an undisclosed speed, the vehicle inadvertently lost motive power. The contact was able to pull over to the shoulder of the roadway, where the failure persisted. The contact also stated that the vehicle required an oil change every month. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the engine. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

While driving uphill on Interstate 15 North near Temecula, California, the vehicle suddenly lost engine power without warning. My speed dropped from approximately 75 mph to around 60 mph in heavy traffic. This unexpected loss of acceleration created an immediate safety hazard, as vehicles behind me were traveling at freeway speeds and I was nearly rear-ended. I had to maneuver from the far-left lane to the shoulder while the vehicle continued to lose power. Once stopped, the check engine light was flashing, and the engine temperature gauge showed extreme heat, raising concern for a potential fire. The vehicle was towed to a Kia dealership, where technicians confirmed a complete engine failure and recommended a full short-block replacement. The vehicle has been regularly serviced and has more than a dozen documented service visits, including visits for ongoing oil-consumption concerns. Despite this, the low oil warning light never illuminated when the engine oil level was low; the only alert that appeared was the routine maintenance reminder. The lack of a low oil warning contributed to undetected oil loss and sudden engine failure. This failure occurred at approximately 92,000 miles and mirrors previously reported engine and bearing defects in similar Kia models. The vehicle and documentation are available for inspection upon request.

There were no known issues with my vehicle not even a check engine light or anything was on. I was driving then the car randomly stopped accelerating. It would only go up to about 25 miles per hour. Something started rattling under the hood and it cut off in the middle of an intersection. I was almost hit because it was a 4 way intersection which put myself and all of the other cars on the road at risk. A police offer had to direct traffic until a tow truck made it. I had to get my car towed to a mechanic shop and I was told my engine blew. I checked for engine recalls using my VIN but nothing came up but my car had the same issue and symptoms as all of the 2020 Kia sportages that did have recalls.

Driving 70mph on the freeway and check engine light started flashing. Car immediately went into “limp mode” and within a few hundred feet went from 75mhp 30mph. Used ODB reader and code p1326 came up for “engine knock sensor”. Engine was two quarts low on oil. No low oil warning. I just had an oil change a month ago and there is no apparent oil leak. When I opened the oil cap small amount of smoke was visible coming up from engine. Car has 75400 miles on it. I reset the code, put 2 quarts of oil and drove 2 miles to a Kia dealership. The said they couldn’t look into it since I reset the code. I drove another 4 miles and the same code and symptoms showed up. Having my car towed home because the dealer can’t inspect until next week. Other Kia’s have had this same error code and were recalled with engine replacement.

Update: after second opinion from another auto shop they said my car entered limp mode to prevent fire. Again, I had no warning! Kia tried to tell me the engine light must have came on and cleared itself (engine lights don’t clear themselves) and they refuse to check the recall fix of the HECU. They tell me the recall has been fixed so it can’t be the problem. Myself and my kids were put at risk as this problem causes risk of wrecks or even fires and Kia is not wanting to take any responsibility for it. These are the same issues as other Kia’s but because of my vin number they won’t even speak to me (literally, called Kia Clarksville and left a message with a woman for service to call me back for repairs and they won’t even call me back to schedule the repair - they are charging me over $6000)

I was driving home and the car kind of jerked, like it was down shifting, and the engine light came on. If I had to stop, it would almost stall out. When I got home I checked the oil and it was bone dry, however, my oil light never came on and I am diligent about oil and filter changes. I added oil to it, but the engine light still is on (flashing). The recall shows two, one for the hitch and one for an engine fire. I only received one for the hitch.

The car started making a knocking noise. I got it checked out and nothing showed up on the diagnostic. Today I was driving and it wouldn’t go over 65 and the engine light keeps blinking.
